DUMP-WAGON.

Patented June 1, 1909.

Application filed May 29, 1908. Serial. No. 136,644.

Beit known that I, JOHN F. ECOARD, a citizen of the United States,residing at Troy, in the county; of Miami and State of Ohio, haveinvented certain new and useful Improvements in Dump-d agons, OfWlllCthe following is a specification.

dump wagons This improvement relates to and particularly to anattachable bed. for the l closed position.

running gear of on ordinary farm wagon, and preferably bottom dumpwagons.

The ob'ect is to construct the box so that it can be readily applied tothe running gear of on ordinaryfarinwagon, supporting samesufficientlyhighfrom the ground to ermit the bottom. doors to openreadily, and l have. so arranged thebottom doors of the wagon box thatthey are readily manipulatedand' the hinge connections of the innerdoorsnre protected bythe formation of the wagonbed. i

In the drawing Figure 1 is a side elevation of the wagon-bed with theouter doors open. Fig. 2 is a. sectional view taken on the line m at ofFig. 1, showing however, the doors in Fig. 3 is an end View showing thedoors in open position. Fig. 4 is e Y to saidboxneerthe bottom.longitudinalshaft, of, with worm gear at each.

end. thereofis shownivotally supported on detail View of thebottoin ofthe box showing th inner doorsend the hinge connections, looking at thebottom from underneath.

Like letters of reference indicate like parts throughout the differentviews. I

The box of the wagon is indicated by the .reference letter a (seeFig. 1) and is formed with open bottom and the doors are lunged saidbox,The usual rand-lever c (see Fig.

3) with the ratchet-pawl connection for opera'ti'ng the longitudinalshaft is employed.

I have shown the wagon box a, formed withfalse bolsters, a, and theguides a projecting'froni the box (see Fig l) are adapted to fit overthe/bolsters on, the run ing gear of theordinnry wagon, and by men. solthe falsebolstersthe wagon box is supported sufficiently high from theground to insure the doors, o (see Fig. 3') opening and shut ting freefrom interference from the ground or otherobstacles. In order to improvethe dumping operation and at the" same time strengthen the constructionof the wegon x box, there are employed two sets of doors The ordinaryand the inner air of doors, a, are hinged shown. The hinge pivots areindicated by, the reference letter, a, and the hinges, a, are of angularshe e, so that when the He s, c, are opened, t e hinges' as well as t ehinge pivots, are located well within the protection of the brace orsupport, a.

From on examination of Fig.2 it, is apparent that the inner ends of theinner doors, (1?, ere'turned up attiie inside edges and the hinges,,o,are then bolted to the body portion of the doors, af so that in theposition shown in that figure, which is closed position, there is oerfect seal for the doors, thereby avoiding t e danger of leakage of thecontents and interference with the operation of the doors. I

Chain cTinnections at each end of the bed extend between the worm gearon the longiairof chains, indicated by the reference etter, b, and twoseparate chains, 1) and b the chain b, at its free end being connectedto one outer door, and its opposing chain, 11 at its free end beingfastened to the other outer door. These chains, b and I), pass overordinary rollers, 11 secured to the inner doors mid also over rollers,I), secured to the bed of the wagon. By operating the hand lever, a, thechain, b, is raised or lowered, and the inner and outer do rs areopeiied or closed. It is apparent by this arrangement of chemconnections there is a. desirable application of ower for operatingthese doors; There bed of the machine with a 100k thereon for thepurposeof regulating the opening of the bottom doors or throwing out ofcommission one pair of: doorso,s;mey be desired. if the hook of thechain, b ,is fastened within the linksof the chsins, bor b, the doors onone in Fig. 4, where one of the hinge plates is;

is s own one c rain, b sus ended from'the rotected by said support fromthe i tudinal shaft, a, and the doors comprising a 'I have so formed thelock side or the other of the bed may be held closed, while the operatoris free to manipulate the other doors, and if it is desired to open onlypartially the doors, the hook of the chain, 11 will be inserted Within alink of the chain, 6, thereby the chain, 1), can only partially operate,and the doors will be operated only a corresponding amount.

My locking devices, I), pivoted to each of the outer flaps or doors andextending through fixed loops, b, on the end of the bed are especiallyimportant in this kind of machine; for it is obvious that the machinemay be standing on an incline, such that the outer doors or either ofthem may tend to close by gravity, whereas in closing it is desirable toclose the inner doors first. For this reason that it will prevent theouter doors closing until the inner ones are closed.

The shoulder, b contacting the lower part of the loop, I) will preventthe closing, of the outer doors until the inner ones reach closingposition, whereupon they will strike the hooked ends, b, of the lock,thereby raising the shoulder, [1 out of normal position to clear thelower part of the loop so that the outer doors can then close. 7

Having thus described my invention, I claim:

1. In a dump w 'agon, a'bed, outwardlyopening doors secured to the sidesof said bed, inwardly-opening doors hinged to the center of said bed, apulley located on said bed vertically above each pair of outer and innerdoors, a pulley on each inner door, cables connected to each outer doorand extended about said bed pulloy and also about said inner doorpulleys, and means connected with the inner free ends of said cables foroperating same to raise and lower substantially specified.

2. In a dump wagon, the combination of a bed, outwardly o ening doorssecured to the sides of said be inwardly opening doors hinged to thecenter of said bed, separate cables for each pair of doors comprising aninner and outer door, and a main cable connected to said door cables,supportin means for each door cable comprising a pul ey, and a pivotedlatch on one door of each air, and means for supporting the free end ofsaid latch, and means for operating said latch during the final movementof said cables, substantially as specified.

3. In a dump wagon, a bed, an arch-shaped central brace portion,vertical extensions near the lower part of said brace portion, aplurality of inner doors, the inner edges of the doors turned upwardlyto conform to the extensions on the brace portion, hinges connected tothe body portions of the doors, ling-e pivots connected to said hingesand located within the central brace portion, sul'istantially asspecified.

4. In a dump wagon, the combination of a bed, an arch-shaped centralbrace portion, a plurality of inner doors, hinges connected to the bodyportion of each door, a reinforcing extension connecting said hinges andbracing said arch-shaped portion, hinge pivots located within said archportion, substantially as specified.

said doors,

my hand this 26th day of May, 1908.
